Matthew 21:1-6 “And when they drew nigh unto Jerusalem, and were come to Bethphage, unto the mount of Olives, then sent Jesus two disciples, Saying unto them, Go into the village over against you, and straightway ye shall find an ass tied, and a colt with her: loose them, and bring them unto me. And if any man say ought unto you, ye shall say, The Lord hath need of them; and straightway he will send them. All this was done, that it might be fulfilled which was spoken by the prophet, saying, Tell ye the daughter of Sion, Behold, thy King cometh unto thee, meek, and sitting upon an ass, and a colt the foal of an ass. And the disciples went, and did as Jesus commanded them.”
There is a sense in which God does not need us or anything we have, but there is another sense in which the Lord does have need for us. Of course, in His omniscience and omnipotence, He arranges and motivates in such a way that He can know ahead of time that He will have that which He needs.
